Spocification forning part of Letters Patent No. l97,453, (lated November 27 1877; application filed May 12, 1877.

To all whom it may concm:

Bet knownthat I, SYLVESTER BRADLEY, of Bloomin gton ,in the county of McLean and State of Illinois, have invented certain new and useful Improvements in Pump-Valves and I do hereby declare that the following is a full, clear, and exact description ofthe same, reference being made to the accompanying drawing, forming a part of this specification, and in which Figure l is a Vertical section showing my improvements as applied to the pipe or cylinder of a pump. Fig. 2 is a top or plan View.

My invention relates to improvements in the class of punp-valves which can be removed for repairs without taking the pump down or to pieces; and the invention consists in the combination of the valve and a frame, to which the valveis Secured, so as to have free vertical play therein, and a valve-seat, all as hereinafter fully described.

A in the drawings represents the section of a pipe or cylinder of a pump, and B represents the valve-seat of the lower valve, which is constructed and secured in the pipe or cylinder in the usual manner. C represents a stem or puppet valve, and c the stern thereof, which passes up through a central hole, a in the metal frame D, and whichis securedthereto, so as to have a free Vertical play through said hole by bending the stem, as shown in Fig. 1, or by a nut and Washer, or any other equivalent device.

The frame D is composed of two or more downwardly-prqjecting arms, d, whichrest on the outer part of the valve-seat when placed in position within the pipe or cylinder of the pump. -The Valve has the requisite vertical play desired inside of the arms which inclose and guide the Valve. Said frameD is designed to be fitted loosely enough within the pipe or cylinder of the pump as to be readily withdrawn therefrom without taking the pump down or to pieces, and also of sufficient weight to hold the valve down in its proper place.

Said frame, with the valve, can be easily and readily removed from the pump for repairs by means of a hooked 'rod or wire, or any other I equivalent device.

I am aware that a compound valve, in con- SYLVES'DER BRADLEY.
